Here's a sample of white calcite on druzy quartz, the calcite has a very strong reaction under the UV lamp as can be seen in the photo . The specimen comes from the Canada Fluorspar Inc. Mine, which was, until recently, mining a fluorite vein in a cluster of fluorite veins that have been mined on and off for decades. The company identified a significant fluorite bearing structure hosted in the meta-sediments which has been intruded by rhyolite sills and dykes. The Mine is currently closed and it may open again, sometime in the future.
